Stay alert. Watch what you are do- ing and use common sense when operating the regulator. Do not use the regulator while tired or under the influence of drugs, alcohol, or medication. A moment of inattention while operating the regulator increases the risk of injury to persons. b. Personal safety Avoid unintentional starting. Be sure the tool switch is off before connecting to the CO 2 Regulator. Do not connect the tool to the CO 2 Regulator with the switch on. c. Always wear eye protection. Wear ANSI-approved safety goggles. d. Always wear hearing protection when using the regulator. Prolonged exposure to high intensity noise is able to cause hearing loss. Use only with tools specifically de- signed for use with bottled gasses. Read tool manual before connec- tion and/or use. b. Regulator use and care f. Do not use the regulator if the Regulator Control Knob does not function properly. Any regulator that cannot be controlled is dangerous and must be repaired. g. Disconnect the tool from the CO2 Regulator before making any adjustments, changing accessories, or storing the tool. Such preventive safety measures reduce the risk of starting the tool unintentionally. Turn off and detach the CO 2 supply, safely discharge any residual pressure, and release the throttle and/or turn the switch to its off position before leaving the work are Store the regulator and gas canis- ter when idle out of reach of children and other untrained persons. A regulator is dangerous in the hands of untrained users. h. Do not exceed 150 PSI input pres- sure. i.

CO 2 Canister Connector Belt Hook Regulator Knob Female Output Connector Bottom View of Item 2. Insert a standard 20 oz. CO 2 bottle (not included) into the opening at the bottom of the regulator. Turn the canister clockwise to screw it into the Connector. Tighten firmly to prevent leaks. 3. 4. 5. Adjust the Regulator Control Knob so that the air output is enough to properly power the tool, but the output will not exceed the tool s maximum air pressure at any time. Adjust the pressure gradually, while checking the air output gauge to set the right pressure range. Inspect the air connections for leaks. Tighten connections to eliminate leaks. Connect Hose to tool (not included) by pressing coupler onto inlet. 7. Connect the Hose to the CO2 Regulator by pressing it onto the outlet. 8. 9. The pressure supplied to the tool can be adjusted by turning the Regulator Control Knob. Turn counterclockwise to reduce pressure. Turn clockwise to increase pressure. The pressure setting is shown on the Output Gas Pressure Dial. Adjust the Regulator knob to the pressure recommended by the tool manufacturer. Do not exceed the tool s maximum air pressure rating. Note: Residual air pressure should not be present after the tool is disconnected from the CO 2 supply. However, it is a good safety measure to attempt to discharge the tool in a safe fashion after disconnecting to ensure that the tool is disconnected and unpowered. 10. As the contents of your CO2 canister are used up, the available pressure will decrease. Available pressure will eventually fall below your regulator setting. The dial will show a lower pressure reading than desired. When pressure is no longer adequate, replace the CO 2 Canister. Dispose of used canisters according to solid waste disposal instructions. 11. To prevent accidents, turn off the tool, detach the CO 2 Regulator from tool and canister, and safely discharge any residual air pressure in the tool after use. 6. The CO2 Regulator has a built in hook that can be used to hang it from a belt. REV 09c SKU 99901 For technical questions, please call 1-800-444-3353. Page 6
